terminal window gets square corners after being maximized

[Random]

After having maximized to fullscreen the terminal window and re-minimized it, its corners are squared and not rounded anymore. It happens one time evey two: when I maximize the window with square corners and re-minimize it, it gets the original round corners. Repeating this procedure gets square corners and so on...

I was able to reproduce this on the same system version (11.10 x64 upgraded from 11.04), but mine restored to square edges every time I restored it from maximum.

Unable to reproduce it on Ubuntu 12.04 x64, installed from scratch. Works fine.

That version has reached EOL since a while, so it will not receive update. If that issue still exist, report again using ubuntu-bug.
